Issue when turning off modem noise on dial-in and dial-up + mgetty

[Orestes LeaL R.]

I have a machine running openbsd 4.3 acting as a dialin server using
mgetty, I need to turn off the modem noise of dial-in and dial-out,
I tried and then I edited /etc/ttys and added -m ' AMT0' to the line
where mgetty is but I add to -D also and when I reboot the server dial-in
service responds in the first request (I do not want this since my config
it's based on rings 2 config and wait 20 seconds for the client to dial  
again

as explained in the home page of mgetty, also I tried to make a 4.6 box a
dial-in server cloning the config but DOESN'T work with 4.6 at least with  
the same config,

 help needed here boys I need to turn off the audio on the modem.

yes: my english it's a mess!

After 4.3, OpenBSD stopped using pccom to use the common com
driver on i386.

That wasn't progress. Capabilites where lost.

I had a perfectly working dialin-dialout setup with getty for a
decade that is now not working anymore (It somewhat work if I reserve
the line/modem for dial-in only. And make sure getty is killed before
doing dial-out)

I have also 2 internal modem (ISA/PCI) that gets detected as having
no fifo (they do have them, they just didn't implement the similated
loopback mode openbsd use to test them). That require the machine
to do 3500+ interupt/second instead of the more reasonable 600
interupt/second. In 4.3, I can force it to use the fifo, but in 4.8
the same hack cause data integrity issue.

/end of rant


Not that I know how to resolve your issue with mgetty, but I would
try on 4.3 first. I mostly gave up on 4.3 and the com driver.

(mgetty -m is a chat script, like -m ' ATM0L0 OK'. mgetty has a
debug log, that can help too.)
